It still has by far the lowest barrier to entry for basic deployments (pick any random cheapo shared web host; FTP your files to it; done) - that counts for a lot in the real world, and I’m sad that nobody else is even trying to compete :(
Still compelling for people who see spiky to high traffic and are happy to have scale reduced to an accounting/budgeting problem, of course, and I'm pretty sure Laravel has something like this.
